Abstract: 874,196. Aircraft take-off monitering instruments. BENDIX CORPORATION. Aug. 11, 1959 [Sept. 4, 1958], No. 27461/59. Class 4. A display system for an aircraft take-off monitor comprises a scale element representing a runway and points therealong and means for continuously indicating on said scale during an attempted take-off the current predicted points at which the aircraft should either be stopped or made airborne. The system comprises an indicator 10 having three lights 11, 12 and 13 respectively marked COMMITTED TO TAKEOFF, STOP and CLIMB and a window covering a scale 15 representing a runway and formed by lines 1 to 14 representing 1,000 ft. spacings along the runway, the upper part of the scale being marked END. The entire scale is coloured to contrast with the colour of three pointers 20, 21 and 22 which move over the scale and respectively denote the position on the runway at which it is determined that the speed of the aircraft carrying the instrument will correspond to the correct take-off speed ; the position on the runway at which it is estimated the aircraft will stop should the brakes be applied and the current position of the aircraft along the runway during take-off. A knob 25 is provided for setting pointer 22 at the correct position on the scale representing the position of the aircraft at the commencement of the take-off run and also for aligning pointer 21 with pointer 22. The instrument is controlled by apparatus comprising a braking computer 30 which calculates the predicted distance from the end of the runway at which the aircraft may be stopped if braked ; a take-off computer 31 which calculates the currently predicted distance from the end of the runway at which aircraft speed with equal take-off speed and take-off can be accomplished and a computer 32 which calculates the present position of the aircraft on the runway. Information on the magnitude of the variables required to make the computations are delivered over leads 41, 42 and 43 from a data collector 40 responsive to signals representing aircraft acceleration, instantaneous ground speed, instantaneous true air speed, aircraft weight, runway friction coefficient, air density and, if desirable, wind velocity. Computer 30 energises a servo 33 which moves pointer 21 along scale 15 and,-when the pointer moves beyond the end of the scale operates a switch 50 to illuminate light 11. Computer 32 energises servo 35 to move indicator 22 up scale 15 from the starting position set by knob 25 to the current position of the aircraft. Computer 31 energises servo 34 to position the predicted take-off indicator 20. The output of servos 33 and 34 is used to operate a limit switch 51 which illuminates light 12 when the take-off indicator 20 is beyond the end of scale 15 and the stop indicator approaches closely to the end of the scale. The output of servos 34 and 35 is connected to a switch 61 which, when pointers 20 and 22 are in alignment, will illuminate light 13 to indicate that the aircraft has reached the correct speed for take-off.
